Manipulate a virtual deck of cards (in ruby!) in your browser

Opal.rb Demo App

This is a quick working example of what's possible using Opal.rb to compile Ruby code into Javascript. A lot of the scaffolding of this app comes from this guide.

The ruby app

Inside app/cards.rb is an idiomatic Ruby model of a deck of playing cards, complete with methods to deal, shuffle, compare cards, etc. This example uses some ruby core modules like Comparable and Enumerable for fully native behavior. If you load this code in a Ruby REPL you can instantiate a PlayingCard::Deck, deal any number of cards (which are then removed from the deck), etc.

Compile to JS

1. Clone the Repo
2. run bundle install and rake build
3. Open index.html in your browser. You should see a <ul> of randomly dealt playing cards if you have JS enabled. See the application.rb file for implementation.
